Kiss fans who saw the rock band on their 2009 US tour had the chance to take the show home with them in their back pockets when they walked out of the venue.
"We do a multi-track recording of each night and make the recording available on a USB drive right at the end of the show," says Gerrit Schumann from German company Music Networx, which makes the recordings.
"We have USB duplicators that do it pretty much automatically at the venue. We stop recording about half an hour before the end of the show and include a download code, with which the fan can then download the encores and remaining 30 minutes online."
Each stick cost about $20 and an artist will get anywhere between 20-50% of the price, he says. With around 1,000 sticks sold a night at 58 dates last year, that adds up to several hundreds of thousands of dollars for the band.
They will do it all again for their European tour this year, where they will also introduce an instant download-to-mobile option.
Kiss, already the masters of music merchandise, are also selling meet-and-greet gig packages for £905 per person in the UK.
